I too only heard today of Trevor's passing.
He died of cancer last Thursday after a brief spell in James Cook Hospital, only a few months short of his 85th birthday.
Trevor was indeed a fine fellow and a genuine old-school folk scene stalwart. He had a wry - and sometimes quite wicked - sense of humour that was balanced by a true compassion. I had the privilege of working closely with Trevor for many years, both on Folk Roundabout magazine and in organising the Nature's World festival, and often travelled with him to Stockton Folk Club in the club's "Ron Angel years". Although he "retired" from both activities around five years ago, he maintained a lively interest in the folk music scene right up to the end; latterly he sang mostly at the Cutty Wren at Redcar. His distinctive presence will be much missed.
RIP Trev. Keep banging on yer bodhran and keep the Salvation Band going up there!
